STEERING WHEEL

An airbag device is moved toward mounting portions and pins are inserted into insertion holes. Slopes at the distal end of each pin come into contact with a locking bar, so that the locking bar rotates and enters a longitudinal groove. When the locking bar approaches a back surface of the longitudinal groove, the locking member is rotated by an urging force of the coil spring and enters lateral grooves. Thus, the airbag device is mounted on a steering wheel body.
